About 1X

We’re building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it’s not.

To do this right, we have to solve robotics, AI, manufacturing - at the same time, at scale, in a form factor that has to be safe enough to live with your family. If you’re inspired by this, you’ll thrive here. We’ve been at this since 2014 and we’re at the point where the hard problems are behind us and the hard work is in front of us.

NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We’re not demoing it - we’re shipping it. We’re excited to meet you, if this excites you.

If you’ve spent your career working on problems that matter and want to see them actually reach the world - this is that moment. We’re scaling, we’re hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.

About the Team

The Supply Chain team at 1X is responsible for building and scaling the global supplier network that powers our humanoid robots. We work closely with Engineering, Manufacturing, Quality, and Operations to bring highly complex electromechanical systems from concept to mass production.

As part of the Supply Chain organization, you will help ensure our products can scale from prototype to volume production through robust supplier partnerships, operational excellence, and proactive risk management. Your work directly impacts product performance, cost, quality, and our ability to successfully ramp NEO at scale.

Your Charter

As the Supplier Development Engineer for Die Casting, you will own supplier industrialization and quality readiness for structural components that form the foundation of NEO’s mechanical architecture. You will work closely with engineering, sourcing, and manufacturing partners to develop robust casting, machining, and finishing processes that deliver lightweight, high-strength components at scale while meeting 1X’s quality, cost, and production targets.
